3pin XLR Audio To Fiber Converter Extender MIC Level And Line Level
MIC Level and Line Level Audio TO Fiber Extender
A mic-level or microphone-level signal describes the voltage generated by a microphone when it picks up sound, typically just a few thousandths of a volt. This voltage varies in response to changes in sound level and distance. Of the four main types of audio signals, the mic level is the weakest and requires a pre-amplifier to bring it up to line level. The microphone level is usually specified between -60 and -40 dBu. (dBu and dBV are decibel measurements relative to a voltage.)
Our Mic- level audio to fiber converter integrates a preamplifier to boost the mic level to the line level. Our Audio Fiber converter can be built to a 1-channel Mic level in and 1-channel line Level out, or 2-channel mic level in and 2-channel line level out, etc.
